INSTALLATION
(7) Remove the option data port insert from the inverter cover.
(8) Set the node address using the two rotary switches on the option unit.
The valid addresses can range from 03 through 7B hex (123 decimal).
The node address must be set to the value as configured when setting
up your PROFIBUS master. The master must be aware of the node
addresses assigned to the FR-A5NP or communications will not be
established. Refer to user documentation for master details.
Do NOT set the address from 7C to FF. If you do, the option unit
and inverter will not operate correctly.
CAUTION
Do NOT set more than one station to the same address on a single
PROFIBUS-DP network.
SW1 is nearest to the LED and sets the most significant digit. For
example, to set the node address to 7B hex (123 decimal), set SW1 to
7 and SW2 to B.
(9) Replace the inverter cover, while making sure that the PROFIBUS
connector is aligned with the option data port window.
(10) Connect the PROFIBUS cable to the inverter by plugging the DB9-
style male connector into DB9-style female connector of the option
unit, which should be visible in the option port window.
